Around 2 AM a earthquake of a 4.5 magnitude was measured just east of Askja. The occasional minor earthquake has been measured there for the past week. The seismicity there peaked at 2 AM and has been stable since. There are still no signs of an impending eruption.
The seismicity was most at the end of the subterranean channel, where the magma continues to push north towards Askja.
The large quakes in Bárðarbunga are interpreted as the results of pressure changes related to the advancing magma.
100000 flights were cancelled during the Eyjafjallajökull eruption. It is doubtful that the same will happen again.
"Right now we're analyzing what was going on. As of now we don't know, but we'll keep analyzing and add it to the data pool," says Sigrún Karlsdóttir,at the IMO.
270 million cubic meters of magma has gathered underneath Dyngjujökull in just one week.
An earthquake of magnitude 5.7 hit Iceland's Bardarbunga volcano overnight.
